7. For the cache module to be replaced, complete one of the following two
options:
■ For cache modules in an M2100 or M2200 enclosure, disengage both
cache module retaining levers, and remove the cache module.
■ For cache modules in a BA370 enclosure, complete the following
substeps:
a. Disengage both cache module retaining levers, and partially remove
the cache module—about halfway.
Caution: You must disable the ECB before disconnecting the ECB Y-cable. (If
the ECB status light is off, this indicates that the ECB is disabled.) Failure to do
so can result in cache module damage.
b. Disable the ECB by pressing the battery disable switch until the status
light stops flashing. The status light should stop flashing in
approximately 5 seconds.
Note: Refer to the documentation that shipped with the ECB for additional battery
information.
c. Disconnect the ECB Y-cable from the cache module.
d. Remove the cache module from the enclosure.
e. Place the cache module on a grounded antistatic mat or in an
antistatic bag.
Note: The DIMMs must be removed for installation in the replacement cache module.
